Everything works perfectly
on the user manual it says it accepts max 32gb memory card. dont use cheap card or it will lag so bad and break records. night recording is pretty good, but not as good on back camera. video exposure is fine but its harder to see details. screen reflection as of mirror is good, you can turn screen off if it distracts you. when reacher max capacity it will record over oldest videos. it has battery but its not capable of sustaining for a longer period of time. overall i am satisfied with this device.
